Understanding the Internet: How it Works

Internet Data Transmission

• The primary technique used by the Internet for transmitting data is packet switching.
• Data sent over the Internet is typically translated into digital signals, specifically binary pulses.

Internet Connection Technologies

• Dial-up technology is used to connect to the Internet using a standard telephone line.
• The main advantage of a dial-up connection is that it is relatively inexpensive.
• Dial-up technology establishes a connection to the Internet by dialing a phone number to access a server.
• A significant drawback of using a dial-up connection is that it ties up the phone line.

Network Infrastructure

• The primary infrastructure used for computers to connect to each other and to the Internet is a network.
• A network can be either wired or wireless.

Wired Networks

• A significant disadvantage of a wired network is that it can be difficult to maintain and move around.

Wireless Networks

• Wireless networks transmit data using radio waves.
• A key drawback of using WiFi for wireless connections is the potential for interference from other devices.
• A key advantage of using radio waves for wireless connections is that they allow for greater mobility.
• An essential component for a wireless router to function in connecting to the internet is an antenna.
• A common challenge associated with using WiFi for wireless connections is the issue of signal range and strength.
